So my partner is very into fitness/health etc and likes to good which isn’t a problem. He does go on about people being ‘fat’ quite a lot, people who I would consider not fat but yes maybe slightly overweight. So the topic comes up regularly (in a jokey way) that he wouldn’t want me physically if I put on weight. This has recently led to a conversation about changing as we get older in relation to our appearance as I feel it’s inevitable that I potentially won’t be as attractive when I’m older to what I am now. Therefore queried whether natural changes would alter his sexual desire. All he could say is it’s science that men want their partner to look good and he needs to be sexually attracted to me to have sex with me. I understand that but feel that it’s very superficial that my aging for example might change that for him. AIBU?! As right now I’m thinking of leaving him as I feel that’s mental. And I’m thinking I’ll just be waiting around to see if/when he no longer fancies me which just feels very depressing.
